People are already speculating about the second generation iPad. We also hear that Apple is working on something speculators call “World iPad”. The “world” in this case means that it will have both GSM and CDMA capabilities making it compatible with phone carriers around the world.

All Things Digital‘ reports that analyst Brian Blair of ‘Wedge Partners’ – a Denver-based company – recently performed channel checks on wireless supplier Qualcomm, and he is sure that the second-generation iPad will contain one of their multimode CDMA-GSM chips.

“Recent checks… suggest Apple is going to be ratcheting down production of the existing 3G iPad over the next two months in anticipation of ramping up a new World iPad that is powered by Qualcomm and will run on both GSM and CDMA based networks around the world,” Blair writes.

This move will allow Verizon Wireless the possibility to offer 3G iPads, without limiting its sales to only Wi-Fi models, which it sells with a MiFi mobile hostpot.

Blair’s discussions with suppliers reveal that the second-generation iPads will be much thinner and made from one piece of metal similar to MacBook Pro’s uni-body construction. As expected it will be much faster and will feature a front-facing camera for ‘FaceTime’ video chats.
